  • Patent number: 12030974
    Abstract: A self-assembled film forming composition for forming a phase-separated structure of a block copolymer layer on a substrate, containing a block copolymer and a solvent, and is configured such that: the block copolymer is obtained by bonding a silicon-free polymer to a silicon-containing polymer that contains, as a constituent unit, styrene that is substituted by a silicon-containing group; the silicon-free polymer contains a structure derived from formula [1-1] or formula [1-2]; and the silicon-containing group contains one silicon atom. [In formula [1-1] or formula [1-2], each of R1 and R2 independently represents a hydrogen atom, a halogen atom or an alkyl group having 1-10 carbon atoms; and each of R3-R5 independently represents a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1-10 carbon atoms, an alkoxy group having 1-10 carbon atoms, a cyano group, an amino group, an amide group or a carbonyl group.

  • Patent number: 12023636
    Abstract: Provided is a method for producing a liquid medium composition, including using a junction conduit structure 10 having a structure in which a first inlet conduit 11 and a second inlet conduit 12 are joined together to form an outlet conduit 13, and flowing a first liquid 1 containing a particular compound into the first inflow conduit 11 and flowing a second liquid 2 containing a linking substance into the second inlet conduit 12, and allowing the flows of the both liquids to join together to mix the both liquids, thus forming a liquid medium composition 3 containing structures formed by the particular compound linked via the linking substance dispersed therein while being flown through the outlet conduit 13.

  • Publication number: 20230392037
    Abstract: The invention provides a composition for forming a coating film having an ability to suppress adhesion of biological substances, a coating film using the same, a substrate for cell culture using the same, a laminated film and a method for producing a cell aggregate(s). The composition for forming a coating film comprises a polymer containing unit structures represented by the formula (1) and the formula (2): wherein R1 to R3, X1, X2, T1, n1, n2 and n3 are as defined herein but not containing a polysiloxane skeleton, and a solvent.
